| Abstract: |
We studied the influence of stellar activity by G-, K- and M-type stars on the detection of transiting planets in the size range of Neptunes down to super-Earths. The main goal is to improve transit detection algorithms by analyzing the stellar activity like stellar spots or flares. We analyzed measurements of space-based missions like CoRoT as well as ground-based observations of solar-like stars with extrasolar planet candidates. We realized that ground based observations have limited capability to detect short-term stellar variations due to atmospheric effects. Otherwise space-based observations tend to measure higher activity of solar like stars than usual. We present some filtering methods to increase the signal to noise ratio for the detection of Neptune- to super-Earth-class planets. |
